task show up itself after maxtime?

Hi,

This is the setting of my task:

task trial
keys F enter
show text "Press F"
sound my_tune1
readkey 1 90000
show text "In the space below please tell us briefly what you were thinking about xxx" 0 -280
silence my_tune1
textbox new 0 0 650 360 white blue 24 arial
textbox 1 focus
readkey 2 9999999
set %my_list textbox
save %my_list
textbox 1 clear
sound my_tune1
set $my_time time-since-start
save TASKNAME $my_time RT

block trial
message Trial
maxtime 1m
tasklist
trial 15
end task
silence my_tune1
end


I set a maxtime of the task so it should end after 1m has passed. However, I found the textbox will appear at the end of the duration assigned. Would anyone know the reason? How can I disable it?
Also, I want the music stops after the maxtime, yet it will have about 1 sec of the music after the maxtime and that it goes away itself. Would be grateful if anyone has any idea of that!

Picking up from my last thread, I would be grateful if anyone know how to keep the music going from where it stops after participants press F and enter some text.

Many thanks!
